Answer:

5a -4

Step-by-step explanation:

Given

(2a + 3) + (3a - 7) ← remove parenthesis

= 2a + 3 + 3a - 7 ← collect like terms

= (2a + 3a) + (3 - 7)

= 5a + (- 4)

= 5a - 4

How do you solve this math problem-2(x+3y)=18

ss7ja [257]

Greetings!

Solve for <em>x</em>.
$-2(x+3y)=18$
Distribute the Parenthesis. <em>How?</em> Multiply all of the terms inside the parenthesis by the number outside the parenthesis.
$(-2)*x+(-2)*3y=18$
$-2x-6y=18$
Add 6y to both sides.
$(-2x-6y)+6y=(18)+6y$
$-2x=18+6y$
Divide both sides by -2.
$(-2x)/-2=(18+6y)/-2$
The Answer Is:
$x=-9-3y$
$x=-3y-9$

Hope this helps.
